Former Jets quarterback Joe Namath, who led the team to its only Super Bowl championship, said in an interview to be aired Sunday on CBS that he suffered some long-term effects from concussions while playing in the NFL.

"I've been through some things medically," Namath told reporter Rita Braver in an interview for "CBS Sunday Morning With Charles Osgood." "I've seen some things on my brain. But I've had some treatment, and I've improved. None of the body was designed to play football. Excuse me, you know, football, we're just not designed for."
